What We Do in Northampton County

Attic Insulation Removal in Northampton County

Air Sealing in Northampton County
Some 67 percent of Northampton County homes heat with electricity, often through attic ducts; their joints and the ceiling's gaps are sealed first.

Homes in Northampton County

Half of Northampton County's 10,600 housing units were built before 1981: 30 percent before 1970, 48 percent before 1980 (nearly all before the state's 1978 insulation rule) and 9 percent in 2010 or later. The largest share went up in the 1970s; fiberglass from those years may have settled, so check its depth against the joists.
